- Description
- Pulsars are observed to be born with mean spatial (3-D) velocities of ~ 450 kms<math>^{-1}</math> [1,2]. Since most stars in our galaxy are observed to possess mean velocities of ~ 30 kms<math>^{-1}</math> [3], it has been suggested such large velocities should be given to the proto-neutron star at its birth. The mechanism responsible for the impulses has not been properly identified, despite of interesting proposals have been advanced [4,5]. Here I identify such a mechanism to be linked to the ''back-reaction force'' of the ''gravitational wave burst'' released during the first millisecond after the core bounce of a supernova collapse. This behavior of the gravity wave is predicted by Einstein's general relativity theory. It turns that the overwhelming population of fast moving pulsars cataloged, compared to the tiny one of neutron star-neutron star binaries [6], makes these objects the most compelling evidence for the existence of gravitational waves, and correspondently points towards the Einstein theory of gravitation as the most correct one.
